The interval parameter specifies the amount of time in
seconds between each report. The first report contains
statistics for the time since system startup (boot). Each
subsequent report contains statistics col- lected during the
interval since the previous report. A report con- sists of
an CIFS header row followed by a line of statistics for each
CIFS filesystem that is mounted. The count parameter can be
specified in conjunction with the interval parameter. If the
count parameter is specified, the value of count determines
the number of reports gener- ated at interval seconds apart.
If the interval parameter is specified without the count
parameter, the cifsiostat command generates reports
continuously.

REPORT The CIFS report provides statistics for each
mounted CIFS filesystem. The report shows the following
fields:

Filesystem: This columns shows the mount point of the
CIFS filesystem.

rB/s (rkB/s, rMB/s) Indicate the average number of bytes
(kilobytes, megabytes) read per second.

wB/s (wkB/s, wMB/s) Indicate the average number of bytes
(kilobytes, megabytes) written per second.

rop/s Indicate the number of read operations that were
issued to the filesystem per second.

wop/s Indicate the number of write operations that were
issued to the filesystem per second.

fo/s The number of open files per second.

fc/s The number of closed files per second.

fd/s The number of deleted files per second.

OPTIONS -h Make the CIFS report easier to read by a
human.

-k Display statistics in kilobytes per second.

-m Display statistics in megabytes per second.

-t Print the time for each report displayed. The
timestamp format may depend on the value of the
S_TIME_FORMAT environment vari- able (see below).

-V Print version number then exit.

ENVIRONMENT The cifsiostat command takes into account
the following environment variables:

S_TIME_FORMAT If this variable exists and its value is
ISO then the current locale will be ignored when printing
the date in the report header. The nfsiostat command will
use the ISO 8601 format (YYYY-MM-DD) instead. The timestamp
displayed with option -t will also be compliant with ISO
8601 format.
